Delta Sigma Insulating Castables

Lightweight Insulating Castables is to conserve heat in furnace. High Temperature Insulating Castables are light but adequately strong and have low conductivity, thus serve as hot face or back up insulating refractory lining.The density range is from 400 to 1600 kg/m3. Additionally, medium purity and high purity grades of the insulating castables are available in the range. For reducing the environment, the high purity (low iron) variety is used.

Delta Sigma Nozzle Opening Compound

It is a free flowing refractory particular material used in the ladle or tundish sliding gate to prevent skulling and steel freeze-off and ensure easy opening at the start of casting.

: It is a highly refractory, granular product with selected particle size and distribution remains flow able at high temperature ensuring consistent and trouble free ladle slide gate operation.

: For achieving the best result it should be preheated at around 100C for about an hour to drive out any physical moisture. The nozzle cavity should be cleaned of slag and any refractory particles before application. The quantity of Nozzle Opening Compound to be applied should be carefully determined so that the nozzle cavity is entirely filled with a slight mound at the nozzle top. It should be applied with a suitable applicator to ensure that the product is applied at proper place.

: Successful operation of ladle slide gate depends largely on the use of proper nozzle filling compounds and operating conditions of the nozzle filling compounds should have sufficient refractories to prevent sintering of the particles at high temperature and good flow ability.

: Excellent nozzle opening performance is ensured and the need of oxygen lancing for opening the slide gate nozzle is minimized also Well block and nozzle life
